We compute our timing results using a Intel i5-7600 CPU @ 3.50GHz CPU,
and a NVIDIA GTX 1080-TI GPU. We use square style and content images
scaled to have the edge length indicated in the top row of Table
REF . For inputs of size 1024x1024 the methods from
[1]} and [2]} ran out of
memory ('X' in the table). Because the code provided by the authors [3]} only runs on Windows, we had to run it on a different computer. To approximate the speed of their method on our hardware we project the timing result for 512x512 images reported in their paper based on the relative speedup for [1]} between their hardware and ours. For low resolution outputs our method is relatively slow, however it scales better for outputs with resolution 512 and above relative to [1]} and [2]}, but remains slower than [7]} and our projected results for [3]}.
